IMPROVEMENT IN TUCK-MARKER S FORSEWlNG-MACHINES.

Specification forming part of Letters Patent No. 158,576, dated J annary 12, 1875; application filed May 7, 1874.

county of Lucas and State of Ohio, have invented certain new and useful Improvements in Tuck-Markers 'for Sewing-Machines; and

we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it,.reterence being had to the accompanyirig drawings which form part of this specification.

Our invention. relates to aniluproved tuckmarker; and consists in the devices and ap pliances, as hereinafter set forth and claimed. In the drawings, Figure 1 is a plan View of our tuck-marker. Fig. 2 isa section of the same taken through the clamp-screw of the guide-plate.

A is a wire, bent at its front end 1-, and here beveled upon its upper side to an edge.

This wire passes ba'ck,is formed into a coil at B, then extends forward, as shown, to G, and is then coiledback upon itself, forming several coils 0. The object ot'i'orming the coil 0 from the endbackward is to give to that portion more elasticity, and to enable the coil to bebrought closer to the needle-bar for formin-gishort tucks. l) is the guide-plate, having 7 I 25th day of April, 1874:. 7

its edge d bent down to embrace the-wire A, and the same-is clamped securely to the bed of the machine by the clamp-screw E. Notches or marks f are made upon the wire A, by which the'breadth of the tuck may beg-aged from the plate at. We form the coil 0 of some five .or six turns, in'order that the requisite elasticity may be given to the coil when it presses of wire bent upon itself at the rear in parallel vertical planes, in the form of an S, and at the front or outer end with spring clampingjaws. This, therefore, we do not claim broad; ly; but

What we do claim, and desire to secure by Letters Patent, is

The tuck-marker herein described, consisting of the wire A B C, bent in the form shown and described, its top front edge beveled to a sharp markingedge, a, and constructed with the scale f, formed upon it, attaching-loop G,

and guide-plate D, secured-to the wire A by v the lip d, which embraces the wire, and on which it is adjusted, and securing-screw E, all constructed, arranged, and adapted to operate substantially as and for the purposes set forth.

In testimony that we claim the foregoing we have hereunto set our hands and seals this JOHN Y. DETWILER. n s ABRAM K. DETWILER. LL. s]
